What to do if Hearthware NuWave Precision shows E1 error?
- EErin AdkinsJul 26, 2025
An E1 error on your Hearthware Cooktop typically indicates that the PIC does not detect cookware. First, ensure you have induction-ready cookware placed on the surface. If the issue persists, the unit might be malfunctioning, or there could be a voltage issue. Check that the voltage is within the range of 85 to 144 volts. Overheating or obstructed air ventilation can also cause this error; in that case, press “Pause/Clear” twice and wait for the unit to cool down. If the internal temperature exceeds 230º F, allow the unit to cool down. If the unit exceeds a temperature 20º F higher than sear, contact customer service.
